Watch: Dhanush's Kolaveri di is a sensation!

Actor Dhanush, who was apparently getting bored in between shots of his wife Aishwarya's film 3, had a brainwave.

And that resulted in Kolaveri di.

The song features in the film and has gone viral on the internet within four days of it being uploaded.

Although the lyrics are mostly nonsensical, by the actor's own admission, that's probably what's working in its favour. The groovy music, coupled with the lyrics, is proving to be a huge hit with the youngsters.

Dhanush has written the lyrics for the song and dedicates it to 'Soup Boys'.

Here's a look at the making of the song. Shruti Haasan also features in the video.
